summary:

The ZXB-F type oxygen lined self-priming pump (steel lined polymer corrosion-resistant and wear-resistant self-priming pump) produced by our factory is an energy-saving pump product developed based on relevant technical data at home and abroad through absorption, digestion, and improvement. This pump belongs to the self-priming centrifugal pump, which has the advantages of compact structure, easy operation, stable operation, easy maintenance, high efficiency, long service life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline. Before operation, it is only necessary to ensure that a certain amount of liquid is stored in the pump body. Therefore, the pipeline system has been simplified and the working conditions have been improved. The overcurrent components are molded from ultra-high molecular weight polyethylene (UHMWPE) or fluoroplastic alloy (F46), with K-type impeller, power impeller seal or mechanical seal. It has excellent performance of no blockage, corrosion resistance, and wear and tear. Exchanging models with ZXB stainless steel self-priming pumps based on the same structure and principle is an effective supplement to stainless steel and has a wider range of applications.

Working principle of ZXB acid resistant self-priming centrifugal pump:
The pump adopts an axial liquid return pump body structure. The pump body is composed of a suction chamber, a liquid storage chamber, a scroll chamber, a liquid return hole, a gas-liquid separation chamber, etc. After the pump starts normally, the impeller absorbs the liquid in the suction chamber and the air in the suction pipeline together, and mixes them in the impeller. Under the effect of centrifugal force, the liquid carries the gas to the outer edge of the scroll chamber, forming a white foam belt of certain thickness and a high-speed rotating liquid ring on the outer edge of the impeller. The gas-liquid mixture enters the gas-liquid separation chamber through a diffusion tube. At this point, due to the sudden decrease in flow rate, lighter gases are separated from the mixed gas-liquid mixture, and the gases continue to rise and be discharged through the pump body outlet. The degassed liquid returns to the storage chamber and enters the impeller again through the reflux hole, where it mixes with the gas sucked in from the suction pipeline inside the impeller. Under the action of the high-speed rotating impeller, it flows towards the outer edge of the impeller. As this process repeats itself, the amount of air sucked into the pipeline continuously decreases until the gas is completely absorbed, completing the self-priming process, and the pump is put into normal operation.

The production, manufacturing, and acceptance specifications of ZXB acid resistant chemical pump products strictly comply with relevant standards and regulations, and undergo bench testing and filing for inspection to ensure the quality of the series of products. The mechanical seal of the fluoroplastic self-priming pump is jointly manufactured by the UK's Glanbogen company and China. It has a reasonable structure, reliable performance, easy maintenance, and energy conservation. It is an ideal equipment for building a civilized factory and effectively solves the problem of leakage. The full range of fluoroplastic self-priming pumps includes 5 models and 10 specifications, with a head of 10-25m, a flow rate of 5-80m3/h, and a self-priming depth of 4-8m.
Some pumps do not have cooling chambers at the bottom of their bearing bodies. When the bearing heats up and causes the temperature of the bearing to rise by more than 70 degrees Celsius, coolant can be injected into the cooling chamber through any coolant pipe joint for circulation cooling. The sealing mechanism inside the pump to prevent liquid leakage from the high-pressure area to the low-pressure area is the front and rear sealing rings. The front sealing ring is installed on the pump body, and the rear sealing ring is installed on the bearing body. When the sealing ring wears out to a certain extent after long-term operation of the pump and affects the efficiency and self-priming performance of the pump, it should be replaced.
